The study investigated the risk of distal forearm fractures in adult Norwegian residents according to regions of birth. There were significant differences in fracture risk between the region of birth categories. Although the magnitude of the rates was different between the birth categories, similar sex and seasonal risk patterns were observed.
Worldwide, distal forearm fractures (DFFs) are the most common fractures in adults. This study compared incidence rates of first DFFs in women and men in Norway by region of birth, age, and season.
We included Norwegian residents aged 20 to 79 years with a first DFF between 2010 and 2020 using data from the Norwegian Patient Registry and population estimates from Statistics Norway. Three countries of birth groups were compared: Norwegian-born, Global North (most of Europe, North America, Australia, and New Zealand), and Global South (Asia, Africa, Latin America, Oceania).
Compared to Norwegian-born residents in Norway, immigrants from Global North had 16% and 37% higher age-adjusted DFF incidence rates in women and men, respectively. Compared to Norwegian-born residents, female immigrants from Global South regions had 24% lower rates, whereas male immigrants from Global South regions did not have significantly lower rates. DFF rates were highest in winter for older men and women regardless of birth category, whereas rates in men younger than 50 years were highest during summer months.
We observed significant differences in DFF rates by sex, region of birth, age, and season. Our findings might have important implications for public health efforts and fracture prevention strategies. Nonetheless, further research is necessary to investigate the underlying risk factors and mechanisms driving these differences.
该研究根据出生地区调查了挪威成年居民前臂远端骨折的风险。出生地区类别之间的骨折风险存在显著差异。尽管不同出生类别之间的发生率幅度不同，但观察到了相似的性别和季节风险模式。
在全球范围内，前臂远端骨折（DFF）是成年人中最常见的骨折。本研究按出生地区、年龄和季节比较了挪威女性和男性首次发生DFF的发病率。
我们使用挪威患者登记处的数据和挪威统计局的人口估计数，纳入了2010年至2020年期间首次发生DFF的20至79岁挪威居民。比较了三个出生国家组：挪威出生、全球北方（欧洲大部分地区、北美、澳大利亚和新西兰）和全球南方（亚洲、非洲、拉丁美洲、大洋洲）。
与挪威出生的挪威居民相比，来自全球北方的移民女性和男性的年龄调整后DFF发病率分别高出16%和37%。与挪威出生的居民相比，来自全球南方地区的女性移民发病率低24%，而来自全球南方地区的男性移民发病率没有显著降低。无论出生类别如何，老年男性和女性的DFF发病率在冬季最高，而50岁以下男性的发病率在夏季最高。
我们观察到DFF发病率在性别、出生地区、年龄和季节方面存在显著差异。我们的研究结果可能对公共卫生工作和骨折预防策略具有重要意义。尽管如此，仍有必要进一步研究以调查导致这些差异的潜在风险因素和机制。
